Diffuse Tracheobronchial Tuberculosis With Left Pulmonary Tuberculosis Displayed on 18F-FDG PET/CT.

A 57-year-old woman was admitted to the hospital with persisting cough and sputum for 2 months. Chest CT revealed multiple nodules in the left lung. 18F-FDG PET/CT scan was carried out to further evaluate these pulmonary lesions. In addition to multiple hypermetabolic nodules in the upper lobe of left lung, diffuse thickening of the trachea and left bronchial wall with increased FDG uptake was also found. Inflammatory granulation tissue with Mycobacterium tuberculosis was confirmed through the pathological examination of bronchoscopy.
